CRUT-CH.

SPECIFICATION forming part of Letters Patent N o. 467,675, dated January26, 1892. Application iiled April l0, 1891. Serial No. 388,358. (Nomodel.)

To @ZZ whom t 'may concern:

Be it known that I, JOHN MGGRAIN, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Crutches, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, in which Figure l is a side elevation ofmy improved crutch, and Fig. 2 is a vertical sectional view of the upperend thereof.

The object of my invention is to provide a crutch which is animprovement in that type of crutches which have springs interposedbetween the upper ends of the side bars and the head ofthe crutch, andwhich shall be simple in construction and cheap in rst cost, and whichwill relieve the shoulder of the user of the full force of the jarincident to throwing his weight thereon.

To this end my invention consists in the construction and combination ofparts hereinafter described, and pointed out definitely in the claim.

Referring to the parts by letters, A A represent the two side bars ofthe crutch, which side bars meet and are secured together by anyappropriate means near their lower ends.

A represents the hand-piece, which eX- tends between and is secured tosaid side bars.

B represents a yoke having in its ends the vertical sockets l) b. Theupper ends of the side bars enter and extend partly through saidsockets, as shown, whereby the yoke serves to brace the side bars and tohold them in fixed positions relative to each other.

C represents the head or saddle, which may be of any approvedconstruction. Secured rigidly to said head and extending downwardtherefrom is the keeper D, having a `vertical slot d, as shown. Thiskeeper enters a ver-v tical slot b in the yoke B, and it is securedtherein by the pin b2, which is secured to the yoke and passes throughthe said slot d. The slot b is somewhat wider than the keeper, wherebysaid keeper andthe head to which it is secured may rock about a centerin or near the pin b2. the head C are two/ sockets c c, located abovethe sockets b ZJ in the yoke, as shown. E E represent coil-springs,which are placed between the yoke and head, with their ends resting inthe sockets h ZJ and c c respectively. When the weight of the user isthrown on the head, the springs are compressed and no jar of anyconsequence is felt. If the weight is thrown on the head either in frontor behind the center, one side or the other of said head moves down thegreater distance in consequence, the pin b2 serving as a pivot aboutwhich said rocking-motion takes place. Moreover, these results aresecured and all the parts held in their proper relative positions by avery simple and cheap construction, containing the fewest possibleparts.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a crutch having springs interposed between its head-piece and theupper ends of the side bars, the combination therewith of the yoke and aguiding and accommodating keeper which permits a vertical and rockingmotion of the head-piece, substantially as and for the purposedescribed.
